Does what the write up says....
Certainly has increased take off acceleration, At 85 and above the car feels different somehow very light and fully responsive literally feels like nothing is too much for it, a little disappointed the programming did not include individual gear change ratios but I still need to get back in there and adjust what I can as I have only adjusted the power as of now, my Vette does have a K&N filter system and axle back SLP loudmouths that have helped with speed improvement gained from the Max program
I purchaced the cortex superchips programmer because I had a 2.73 rear gear and was changing it to a 3.42..I started to buy a Hypertech programmer but, the Hypertech will not, I repeat will not except the new gear ratio...Not only does the Cortex except the gear change it has changed my car to a whole new car..The performance option on the Cortex is great..With the gear change and the reprogramming has really changed my car... I HIGHLY RECOMMEND THE SUPERCHIPS CORTEX PROGRAMMER. In my opinion the only way to get better out of a stock engine is to do a dyno tune...Very Happy..
